The German TerraSAR-X radar satellite, operated by the German Aerospace Center (DLR) and Astrium, has been switched into a new wide-angle view mode allowing the satellite to record image strips over 200 kilometres wide. "The satellite does so by sweeping this large area in multiple stages, very quickly pivoting the radar beam numerous times across the direction of flight," explains DLR mission manager Stefan Buckreuss.
On 15 June 2007, the German TerraSAR-X radar satellite was launched from Russia's Baikonur Cosmodrome in Kazakhstan marking the beginning of a new era in German remote sensing. In its fifth year in space TerraSAR-X has served its planned life-span, but is expected to continue functioning for several years. "TerraSAR-X has now been operating almost flawlessly for five years.
A conference of geological and scientific experts met in the southern Chilean city of Punta Arenas last week to discuss using the TerraSAR-X satellite system to assist Chile in predicting volcanic eruptions. The satellite, which has been in orbit for nearly a year, could provide Chile with significantly advanced warning of volcanic activity and tsunamis.
A new satellite image that shows the likely spread of oil from the Rena suggests things may be worse than many realise.
The satellite image was captured by DLR, the German Aerospace Centre, by its TerraSAR satellite on Friday and shows the likely spread of oil from the ship, which remains stuck on the Astrolabe Reef off the coast of Tauranga.
The crater of the Chilean volcano Puyehue displays a striking, circular outline in this image from the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) TerraSAR-X satellite – so this was not the culprit when a volcano in the southern Andes erupted on 4 June 2011.
The first satellite image of the Ukrainian site was acquired by SPOT1 only ten days after the explosion demonstrating the value of Earth-imaging satellites in responding to natural and man-made disasters
Technology has evolved in the 25 years since the Chernobyl explosion and Astrium GEO-Information’s satellites continue to keep a watchful eye on the zone.
